Method Detail

values

public static DiskCachedTile.TileAction[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DiskCachedTile.TileAction c : DiskCachedTile.TileAction.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DiskCachedTile.TileAction valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getAction

public int getAction()

Retrieves an int associated to this action for interoperability with CachedTile interface.

Returns:

an int associated to this action for interoperability with CachedTile interface.

getDescription

public String getDescription()

Retrieves a description of this action

Returns:

a description of this action

get

public static DiskCachedTile.TileAction get(int actionValue)

Reverse lookup.

Parameters:

actionValue - integer value of the action

Returns:

the corresponding TileAction

getDefault

public static DiskCachedTile.TileAction getDefault()

The default action.

Returns:

the default action.
